Patent number: 11379838Abstract: The present invention includes systems and method for generating Virtual IDs (VIDs) and corresponding Virtual ID Chains (VICs) to anonymize and represent transactions between users, data sources, Virtual ID Management Platforms (VMP), and Third-Party Service Providers (TSPs). VIDs of embodiments are virtualized identifiers that may be used to anonymously and uniquely identify transaction participants. VIDs may be generated in a distributed manner as a party receiving transaction-related information generates a VID corresponding to the sending party. VICs of embodiments are virtualized arrays of VIDs that represent the sequence of interactions between parties to a transaction. VICs are preferably stored in association with transaction logs descriptive of the transaction represented by each VIC to facilitate subsequent processing. A VIC may be iteratively resolved to obtain one or more non-virtualized identifier corresponding to transaction participants represented by the VIC.Type: GrantFiled: February 5, 2020Date of Patent: July 5, 2022Assignee: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventors: Kam Hong Shum, Chi-Kwong Hui

Patent number: 9668541Abstract: An article of footwear has a shoe upper, a sole connected to the shoe upper and the sole is provided with peripheral walls which together define a cavity therein. A layer of material extends across and is connected to the walls or adjacent to the walls at a perimeter of the layer of material, the layer of material dividing the cavity into at least a first chamber and a second chamber. The layer of material and the walls on one side of the perimeter of the layer of material define the first chamber, and the layer of material and the walls on the other side of the perimeter of the layer of material define the second chamber. The sole is configured such that movement of the layer of material within the cavity causes simultaneous changing of interior volume between the chambers and thus pumping of air into or out of the chambers for air circulation of the article of footwear.Type: GrantFiled: May 23, 2012Date of Patent: June 6, 2017Assignee: CEDAR TECHNOLOGIES INTERNATIONAL LTD.Inventors: Neville Ka Shek Lee, Chi Kit Chan, Samuel Sing-Kwong Hui

Publication number: 20050235140Abstract: A method and system for long term electronic document archiving. The system collects a certificate revocation information for a certificate from a certificate authority that indicates the validity of the certificate used in an electronic document. The certificates are collected from a certificate authority. The system then generates at least two layers of signature and timestamp from the electronic document, certificate revocation information collected, and the collected certificate. Cryptographic primitives of different strength are used, and the two layers of signature and timestamp generated have different cryptographic strengths. The signature is generated using a system signing key whereas the timestamp is generated by an external entity. A digital aging token is then formed by combining the original electronic document, certificate revocation information, and certificate collected to the layers generated.Type: ApplicationFiled: March 11, 2005Publication date: October 20, 2005Inventors: Chi-kwong Hui, Kam-pui Chow, Chan-fung Chong, Kwok-hung Pun, Wai-wan Tsang, Hak-wai Chan, Kin-ying Yu

Publication number: 20050043929Abstract: A method and system for normalizing optical spectra using a non-uniform segment normalization. A spectrum is obtained and is represented as a function of wavelength as an amplitude at each of a plurality of wavelengths. At least one segment of the spectrum is selected, each selected segment being bounded by an upper wavelength and a lower wavelength. A normalization factor is computed as the sum of the areas for each of the selected segments. The spectrum is normalized by dividing at least one amplitude of the spectrum by the normalization factor. Segments can be selected with different wavelength ranges, that is, segments can be non-uniform. Test specimens can be categorized based on an analysis of normalized spectra. In particular, the specimen to be tested can be human cervical tissue, and the state of health of the tissue can be determined.Type: ApplicationFiled: June 18, 2004Publication date: February 24, 2005Applicant: MediSpectra, Inc.Inventors: Peter Costa, Kwong Hui, Robert Nordstrom

Publication number: 20030161472Abstract: A server-assisted computational method for computing the RSA cryptography is delineated in this document. The method enables public-key functions on the resource-constrained devices, such as a mobile phone or a PDA, by leveraging the rich computing resources provided by the server-grade computers on the network. Public-key processing, which is computationally intensive as commonly known, if loaded solely on the constrained device, would easily overwhelm the processor capacity and electrical power supply. The server-assisted method enables such device to drive a powerful server computer on the Internet to carry out the public-key number-crunching job for its sake. Some near-completion results are communicated back to the device. From that, the final public-key cryptograph is derived. Privacy and security are the utmost important considerations in public-key systems. The present invention ensures the privacy of the device by blinding the server of the secret message and the crypto keys of the device.Type: ApplicationFiled: February 27, 2002Publication date: August 28, 2003Inventors: Chi Hung Tong, Chi Kwong Hui, Ada Wai Chee Fu, Francis Chi Moon Lau

Publication number: 20020133073Abstract: A system and method for classifying specimens using a plurality of spectral data types. Spectra are recorded as amplitudes at a series of discrete wavelengths. Pluralities of reference spectra are recorded for specimens having known conditions. A spectrum of a first type is observed for a test specimen. The specimen is characterized as to a first known condition. In the event that the specimen does not exhibit the first known condition, a spectrum of a second type is observed and analyzed to determine which of a plurality of conditions is to be ascribed to the test specimen. In some embodiments, the test specimen can comprise human cervical tissue, and the known conditions can include normal health, metaplasia, CIN I and CIN II/III.Type: ApplicationFiled: February 8, 2002Publication date: September 19, 2002Inventors: Robert J.

Patent number: 6421553Abstract: A system and method for classifying tissue by application of discriminant analysis to spectral data. Spectra are recorded as amplitudes at a series of discrete wavelengths. Pluralities of reference spectra are recorded for specimens having known conditions. The reference spectra are subjected to discriminant analysis to determine wavelength regions of interest for the analysis. A plurality of amplitudes are selected for the analysis, and are plotted in an N-dimensional space. For each plurality of reference spectra corresponding to a specific known condition, a characteristic point is determined and plotted, the characteristic point representative of the known condition. A test spectrum is recorded from a test specimen, and the plurality of amplitudes corresponding in wavelength to the wavelength regions of interest are selected. A characteristic point in N-dimensional space is determined for the test spectrum.Type: GrantFiled: December 15, 2000Date of Patent: July 16, 2002Assignee: MediaSpectra, Inc.Inventors: Peter J.
